Of course it is worrying reading all the posts about freezing etc and I won't lie and say it hasn't happened to my K3 - very disappointing after my K2 only froze once in a year that my new model has frozen and done restarts several times in less than a week of owning.
But the great thing about Amazon is they will fix this and promptly. Already people are testing the new firmware out which should stop all the problems. So it should just be a matter of days. Hopefully by the time you get your new Kindle, a new fix will be ready so you won't encounter any disappointment.
Apart from that it is a beautiful device and an absolute joy to read on
